According to information from the Madrid Emergency Force, the incident occurred on Manuel Maroto Street, Puente de Vallecas District, at around 3pm on September 13 (local time).
The explosion was believed to be caused by "gat accumulation," according to a spokesman for the city's fire department.
There were 13 Samur - Civil Defense teams and 18 fire teams of Madrid city, including the professional dog unit, present at the scene.
Many units of the Madrid Community Emergency Medical Service (SUMMA 112) have also been mobilized.
Meanwhile, the Madrid City Police's Aviation Support Team is using unmanned aerial vehicles (UAVs) to provide assistance.
Currently, the search and clearance of the rubble is still taking place to ensure that no one is trapped in the building. However, the machines have not been used because of concerns about the risk of collapse when strongly affecting the project, which was severely damaged.
Madrid Mayor Jose Luis Martinez-Almeida expressed concern in a post on his social network X, saying that the situation at the scene continued to be closely monitored.
